does anyone know what size vband clamp is used on our 50 trim manifolds? Im having a slight leak with the one supplied with the kit ive taken it off and even put some sealant on it and tightend it up as much as it would go it has a slight gap where it bolts together

 

if you're talking about the wastegate flange, its a 44mm.

 

If it is at your wastegate, I had the same problem. I noticed it when I saw the black exhaust soot on my radiator. I took mine off and angled it so that where it mates up w/ the bolt is pointing at a 45 degree angle w/ the bolted side still toward the frpnt of the car. Sorta up and not directly at the radiator. Tightened it up good. Heated up the manifold by running the car, let it cool and tightened again. No more soot. You wont be able to get the clamping surface to meet at the bolted side no matter how much you tighten it.

 

i feel dumb i knew it was a 44mm wastegate haha ill try and tighten mine up some more
